Application filed September 14, 1921. Serial No. 500,528.

To all whom it may concern Be it known that I, BURT A. PETERSON, a citizen of the United States, residing at- Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Means for Locking Yarn Carriers upon Their Supports, of l which the following is a specification.

This invention relates particularly to improvements upon the construction shown in the Colman Patent No. 1,329,5O l,dated February 3, 1920. The advantages derived from the invention will be apparentas the description proceeds.

In the accompanying drawing, Figure 1 is a longitudinal central sectional view. Fig. 2 is a fragmental side view'of the cheese arm. v

The form of yarn carrier herein shown is identical with that shown in the co-pending application, of Howard D. Colman filed September 14, 1921, Ser. No. 500,512. The yarn carrier comprises a tubular section A adapted to fit upon a suitable spindle or pivot and a rotatable section B upon which a yarn mass may be built.

The support'upon which the yarn carrier I is mounted may be of any suitable character,

that herein shown comprising an arm 1 havin an outer end portion 2 of generally circu ar form. In the end portion 2 is a circular depression 3. A spindle 4 is fixed to the arm 1 at the center of the depression Surrounding the base of the spindle and seated in the depression 3, is a sheet-metal housing 5 having a peripheral wall 6 and an end wall 7. The end wall 7 has an opening 8 through which the spindle proj ects.v The housing 5 is held tightly against'the bottom 60 9 fitting within an annular groove 10 in the spindle and bearing against the end wall 7.

curved leaf spring 13 having sockets 14 for,

the balls.

of the depression 3 by means of a split ring 7 On the inner end of the section A of the yarn carrier is a diaphragm 15, to the pe-- riphery of which is secured a flan'ge or ring 16. The ring 16 has an inturned annular v,flange 17 adapted to be engaged by' the balls 12. i p t In use, the operator mounts the yarn carrier on the cheese arm 1 by slipping the tube A upon the spindle 4 until the flange 17 has passed the balls 12. The parts are so proportioned that the pressure of the balls against the flange 17 holds the diaphragm 15 against the end wall 7 The yarn carrier is thus held in a definite invariable position upon the cheese arm. I

7 When the formation of the cheese has been completed, the operator pulls the cheese off the spindle, the spring 13 yielding to permit the flange 17 to pass the balls 12. 7 When any of the parts need repair or replacement, the split ring 9 is removed, whereupon the housing 5 may he slid off the spindle 4, and theloalls 12 and spring 13 removed from the housing.

Itwill be apparent that the means for locking the yarn carrier upon its support is very simple and therefore inexpensive to manufacture, that the moving elements are not subject to rapid wear or, very liable to accidental injury, and that repairs may be easily and cheaply made when required.

I claim a my invention:

1. The Combinationfof an arm having a circular depression at its outer end, a spindle depression, a sheet-metal housing having a peripheral wall and an end wall, said end wall having an opening through which the spindle projects, the spindle having an anrigidly secured to the arm centrally of the nu1argroove, a split ring seated in the groove and bearingcagainst said end wall to hold the housing against the bottom of the depression, said housing having two diamet- 1 rically' opposite openings in its peripheral wall, balls projecting partially throughsaid openings, a curved leaf spring having sockets .to receive said balls, and @a yarn carrier adapted to be mounted upon the spindle and i opening, a spring behind said ball, and a yarn carrier adapted to be mounted upon the spindleand having an annular member surrounding the housing and arranged to'be engaged by the ball.
